Cold Traps - Cold Fingers KF54V

Typ KF54V-K16-Z-18C

Typ KF54V-K16-Z-DSS2000

Construction, Operation And Principles

Cold traps are used in conjunction with vacuum pumps to collect condensation produced from humidity or solvents and these cold traps can be used for many different tasks. The most common application is collecting condensation produced from humidity or solvents from rotating discs, vacuum pumps or high vacuum systems that use oil diffusion or turbo-molecular pumps. In this case a common coolant such as liquid nitrogen (LN2) or dry-ice (CO2) with acetone is normally used.

Cold Traps – Different Versions

Simple cold traps, which are also known as cold finger condensers, are used in conjunction with vacuum pumps and the condensation is forced out of the humidity or solvents used in the chemical applications. The cold trap is used to protect the vacuum pump in this case and the speciality of this type of construction is that the user does not need to use a stand to hold the cold trap. The cold trap has a rim, which is hung inside the Dewar-flask’s support ring. The cold trap can be changed very quickly without any problems arising.

Cold Trap, two Sections

Typ S 54V-K16-Z

A special version is the two section cold trap. It has a KF NW 50 flange as the connection part. This type of cold trap enables the condensation area to be separated from the upper section of the cold trap. This ensures that the removal of the condensation and the cleaning of the cold traps can be carried out very easily. This version is also suitable for when a cold trap has to be permanently installed inside an apparatus, so that only the lower section of the cold trap has to be removed in order to empty out the condensation. The KF NW 50 flange connecting piece is secured in place using a spring Aluminium clamp and this is included in our scope of delivery.
